Use MinRevTTL instead of constant

[juagargi]

In SCIONLab, if we change the value path_mgmt.MinRevTTL from 10 to e.g. 20, some UTs in beacon_srv won't pass. Using the constant MinRevTTL instead of hardcoded 10 fixes them.

path_mgmt.MinRevTTL / time.Second

I think using path_mgmt.MinRevTTL.Seconds() would be good, or is there any advantage to use division?
